Neosporin is for humans. He's going to get an infection, take off that
damn harness and let him inside, give him a bath no shampoo, towel dry
until morning when you can take him to the vet.

I KNOW not to put the harness back on him! My question is NOT about the
harness it's about what to do to the rawness until I can take him to
the vet whenever the vet opens.
No puppy should be an outside dog. Remove the harness until it heals and then get a rolled leather collar instead.

DO NOT PUT IT ON AGAIN
